Poor service

I am dissatisfied with the service I have received from Gaby at Motus Renault in Fourways. It has been over three weeks, and I am still waiting for feedback on how to proceed with getting my car repaired. I was promised an email and a call as soon as the foreman gave the go-ahead for the repair. However, I have had to initiate all communication myself. Despite being promised updates each time I call, I have yet to receive any follow-up or the promised email. I do not understand why it is taking so long to get authorization from the foreman to fix my car.
